also allow the user to test footwear. Insertion of the banana plug
on the wrist strap cord activates the wrist strap tester circuit and
deactivates the footwear test circuit.

The unit comes equipped with a 9 volt alkaline battery. For AC
operation, plug the optional AC adapter into the mini phone jack
located on the upper left hand corner of the tester. AC adapters
LOW BATTERY INDICATOR
The Combo Tester includes a low battery indicator alarm circuit.
If both the audible alarm and indicator LED turn on during use,
discontinue testing and replace the battery. The tester will
continue to operate with a weak battery, but results should not be
considered accurate.
The battery can be easily replaced by removing the battery
compartment cover on the back of the unit and installing a new 9
volt battery.

Figure 5. Testing the wrist strap
4. Lighting of the green “PASS” LED indicates that the wrist strap
and ground cord assemblies are functioning properly.
5. If either “FAIL LO” or “FAIL HI” LEDs light and the audible
indicator sounds, the wrist strap wearer should check the wrist
strap assembly immediately.
TESTING FOOT GROUNDING DEVICES
Combo Tester. The following instructions are intended for use
while wearing foot grounding devices. When using a Footwear
Tester that does not use a split FOOT PLATE, one needs to
test one foot at a time; best practice is to raise the other foot
off the floor. When testing conductive shoes, or foot grounders
worn on both feet, test each foot separately to test the separate
path-to-ground. If the floor is an ESD floor, placing the other foot
on the floor may result in erroneous test results. Care should
also be taken not to create (hand resting on wall or bench) other
paths-to-ground.
